Usage:
SikaChapdur® Premix BA is ideal for use in the following applications:
- Concrete Surface Repair: For repairing cracks, holes, and damaged areas in concrete surfaces in both vertical and horizontal applications.
- Industrial Flooring: Suitable for resurfacing and repairing industrial floors that are subjected to heavy traffic, impact, and mechanical wear.
- Warehouse and Factory Floors: Used for the repair of floors in warehouses and factories where heavy machinery or forklifts cause surface damage.
- Parking Decks and Garages: Ideal for the resurfacing and repair of concrete floors in parking decks, garages, and ramps.
- Structural Concrete Repair: For use in the restoration and rehabilitation of structural concrete elements subjected to environmental damage.
- Aesthetic Concrete Repairs: Used for applications where a smooth finish and appearance are important, such as decorative finishes and smooth floors.
Application:
- Surface Preparation: Ensure the surface to be repaired is clean, dry, and free from dust, grease, oil, and other contaminants. Remove any loose or deteriorated concrete by grinding, sandblasting, or using a chipping hammer.
- Mixing: SikaChapdur® Premix BA is a ready-to-use product that does not require mixing. Simply open the packaging and apply directly to the prepared surface. If necessary, add water to adjust the consistency for specific application requirements.
- Application: Apply the repair mortar with a trowel or spatula to the surface, ensuring an even, smooth application. For large surfaces, use a float or screed to level and smooth the surface. For vertical applications, apply in layers to achieve the desired thickness.
- Curing: After application, allow the repair mortar to cure for the recommended period (typically 24-48 hours, depending on temperature and humidity). Ensure the surface is kept moist during the curing process to prevent premature drying and cracking.
- Cleaning: Clean tools and equipment immediately after use with water before the material sets.
Coverage Advantage:
SikaChapdur® Premix BA offers excellent coverage with minimal wastage due to its high bond strength and ease of application. The typical coverage is approximately 1.5–2.0 m² per 25 kg bag at 5 mm thickness, depending on the surface texture and repair conditions. The product is designed to provide durable repairs with minimal maintenance required, making it a cost-effective solution for restoring concrete surfaces. Its ease of use, long-lasting results, and minimal maintenance needs make it an ideal choice for both professional contractors and DIY enthusiasts.
